TO ALL WHM IT MAY CONCERNE l Be it knownthat we, J. SCOTT and S. H. LA RUE, of Lewisburg, in the county of Union, and State of Pennsylvania, have ninvented a new and useful Improvement in`School-Desks and Seats; and we do hereby declare that the following is e. full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification,'in whichv Figure 1 is a rear View of our improved desk and' seat. Figure 2 is a vertical section ofthe same, taken through the line a: '2, fig. 1. .Figure 3 is a detail view .of the hinge by whichthe leaf is hinged to the desk., -Figure 4 is a detail view of another forni for the same. r Similar letters of reference indicate corresponding parts.

Our invention has for its object to so improve the construction of school-desks4 and seats as to make them more convenient in use and noiselcss in' operation; and it consists in tho construction and colnbination of the various parts, as hereinafter morefully described. v

Aare feet or supports, which rest upon and are firmly secured to the door. The feet Ahave grooves formed in their inner sides, lto receive thel upright bars B, theA upper ends of which are attached to or form-a part ofthe desks. The lower parts of the uprights B slide up and down in the grooves in the feet A, and are secured in place, when adjusted, by screws or bolts passing-through slots in one or the other ofthe parts A and` B, and screwing into the other one of said parts. This enables the desk to be adjusted to accommodate alarge or small scholar, as may be desired. The book-box C of the desk is mudo inthe form shownin the drawings, and is provided with a lid or lids, D, which gives access to the interior of said box. The lids D are hinged at their upper edges, and are provided with book-racks, E, permanently attached to their lower sides, in which the books may be placed and held open while being used by the scholar. It' desired, slidingr racks, F, may be used, made in substantially the form shown in gs. 1 and 2, which grasp the upper end of the open book and hold it while being used. The racks F, when not in use, are slid down into the interior of tho desk, entirely out of the way. This construction of the rack enables it to he adjusted to large or small, books, as may be desired, and also brings thescholar better under the view ofthe teacher. G arelcaves, which are hinged to the edge of the desk in such a way that they may be folded or turned downward or upward, to allow the scholar more convenient ingress to and egress from his desk, and sothat when `extended horizontallyr its edge rnuy form a close joint, and when lowered or folded down into a vertical position, it may form a square corner with the edge of the i desk. This is effected by grooving the edge of the leaf, as shown in iig. 2, and by the peculiar construction of the hinges by which the leaf is hinged to the desk. H are the hinges, which are made in the form of straps, pivoted to cach other, and attached to the edges of the desk and leaf, or to Ranges formed upon said leaves in such a way that no part of the hinge may project above the upper surface of the leaf or top ofthe desk, leaving said surface perfectly smooth, and suitable for use as a writingtable. If desired, the hinges may be made in the form shown in iig. si, that is to say, double-jointed, so that when the hinges I are used the leaf may be folded back upon the top ofthe desk, if required.

The leaf Gis supported when in a horizontal position by the sellacting jointed brace or braces J, thejoint at the centre of 'which is so formed that when the leaf is raised or lowered, the brace J will drop outward` and lock itself, holding the leaf in a horizontal position, as shown in g. 2. One end of the jointed brace J is pivoted to the under side of the leaf G, and the other end to the forward side of the bookbox C. One or the other of the ends of the jointed brace J, it is immaterial. which, works in a groove, so that the leaf Gr may be `raised. to or beyond a vertical position. K are the uprights that support the seat L, and which work up and down in grooves formed in the, inner sides o f the forward parts of the feet A, being held in position, when adjusted, by screws or bolts passing through slots in one ofA the parts A and K, and screwing into the other of said parts. The rear part of the scat L is pivoted or hinged to the upper ends of theluprights K in such a way Y that the seat may be turned up into a. vertical position, to facilitate the passage of the scholars to and from their places. The forward part of the seat L is supported by the rod M, the upper end of which is pivotedto the forward part of the under side of the seat L, and the lower end of which is pivoted to the lower end of the bm* or crank N, the upper end of which is pivoted to the upright, K, as shownin iig. 2. This consti-notion supports the seat firmly, allows if; to be readily raised and lowered, and causes `il; to Work Without noise.

We claim as nem-angl desire to secure Letters Patcntl. The combination ofvthe grooved support A, slotted guides B, desk C, hinged leg G, brace J, verticallysliding support K, seat L, brace M, and crank N, all constructed and arranged as described, for the p11-spose specified.

2. The'jointed seat-brace M N, formed by the combination of the pivoted bar M and pivotcd bai' N, in combination wiLh the seat L and seat-uprigllts K, substantially as hereinV shown and described, and for the purpose set forth. I

The pivoted and sliding scllocking joincfl brace J, in combination'with the lea'WG and boolvbox C, subsbantially as herein shown anl described, and for the'purpose set forth. Y W
